Abstract

The Rockall Trough presents many problems for geophysical analysis, including the generation of deep water bottom and complicated interbed multiple series, severe attenuation of incident energy, and disruption by pervasive Tertiary intrusives. The acquisition and processing parameters of a composite seismic survey conducted in 1989 were based on conclusions drawn during an intersecting survey carried out in 1987. Pre-stack depth migration was applied to the 1989 data set to improve imaging. Velocity control was provided by the integration of coincident expanding spread and sonobuoy data. The pre-stack depth migration is then further expanded to encompass the deepest limits of the composite deep seismic data sets.
